I have all of my models-- how do I bring them into blender?
Welcome!

As I get you correctly, you won't need to care about modeling and you will get a complete model with texture, normal/ambient occlusion map and so forth.

To check what task will still be up to you, you might check for common workflows:


What is the workflow to create animation in Blender?
Unfortunately, it is quite a bit more than "just animating".


Since I am also a beginner in Blender, I can't speak from much personal experience. Here I have put together some (free) tutorials that have helped me to make my first steps. (There are thousand of other really good tutorials out there on Youtube, just search for them! Also Blender.org, Udemy and other pages have good, but often paid tutorials)


(!) You might still get your hands on some tutorials on basic modeling to deal with most likely upcoming problems!
For example:

Rigging:
Most possibly your task starts with rigging your models for animation. It essentially adds controls to your objects for animation, and defines what and how something moves or deforms.
For a perfect start into rigging go trough this series:

Animation:
Here you get a brief introduction into the concept of manually animating simple models.

(?) Dynamics &amp; Simulation:
A start in rigid body simulations/animations as if you might want to make simple physic animations.

And always work with reference material for your animation!

Tip: If you need study material for movement of living beings, just search for "Muybridge" on Google Pictures!


(?) Lighting, Rendering &amp; Compositing
I don't know if you want to render your animations in blender or bake &amp; export them to other software, say a game engine. As I never used blender to render my animations, I do not have any repository of tutorials on that. But you might just check the Youtube Channels I mentioned as well as the following and might find some good tutorials for your needs:
